Discussion

Haplocladium angustifolium occurs in many of the same areas as H. microphyllum but is easily distinguished by the abundant, scattered, subfoliose paraphyllia and stronger branch leaf papillae. The species is more likely to be confused with H. virginianum but the two are distinct in their branching patterns, different branch leaf apices, and laminal cell papillae. These two species are not currently known from the same region in the flora area.
